Any factory or plant guys out there recognize these things?

[mn9000]

Found these hard plastic or PVC items inside an abandoned chemical factory sometime back. They are stamped with the letters "H.H." followed by a 4 digit number. For the life of me I cant find any information online about any manufacturer that corresponds with the letters H.H. Any help is greatly appreciated!

ps--- These may be fairly old, the plant has been closed down for years and years.

From my automated packaging days, the tapered screw looks like a bottle auger feed screw. It's used to convey plastic bottles through an automated bottle fill system.

Second thought, since the auger screw appears to be massive, it's probably used to feed chemicals in powder form, to a packager or to a hopper.

Definately a feed screw and star wheel for a bottling machine.
